Uninterruptible Power supply unit for fire protection and voice alarm system
Uninterruptible Power supply unit for fire protection and voice alarm system, compliant with European standard EN54-4:1997+A1:2002 +A2:2006. The device integrates DC-Ups “All In One” CBI with different battery sizes and two independent outputs, controlled by an internal electronic circuit breaker. The device can supply the load while charging and testing the battery. When mains failure occurs, the load continues to be supplied by the battery without any output interruption. In any situation the battery is tested and temperature charging compensation is performed thanks to the temperature sensor probe RJTEMP. With DPY353 it is possible to monitor the state and the alarms of the system, all of them transmitted by Dry contact. Alarms Type: Battery Fault (Internal Impedance), Mains failure, Generic Fault, battery disconnected, battery element in short circuit.
